Complete Genome Sequence of Caulobacter crescentus Bacteriophage φCbK

phi CbK is a B3 morphotype bacteriophage of the Siphoviridae family that infects Caulobacter crescentus, the preeminent model system for bacterial cell cycle studies. The last 4 decades of research with phi CbK as a genetic and cytological tool to study the biology of the host warrant an investigation of the phage genome composition. Herein, we report the complete genome sequence of phi CbK and highlight unusual features that emerged from its annotation. The complete genome analysis of the phi CbK phage provides new insight into its characteristics and potential interactions with its Caulobacter crescentus host, setting the stage for future functional studies with phi CbK.
